This version adds a Reverse clip option to Clip Jobs that creates a backwards clip.The list of audio/video bitrates can now be customized in custom rendering profiles. New release also fixes several bugs and crashes, including a very annoying bug that caused project files to seem corrupted."

Then simply to convert all videos and pictures to wanted format. Like encode few different encoded video to same with same container in very simple manner and convert all image files to same scale and format and attach soundtrack as well.

Because this is an extremely generic use case. When editing video, most often users need to cut at a specific frame not neccesarily time. Unless the user knows that frame 4923 is the one they want before hand somehow, they need to see and playback the video. Now can it be done using a command line and a separate window? Yes. Is that more cumbersome than a graphical UI? Yes.

You'd use SMPTE format - specify the time and the frame, e.g. 00:03:56:23.

Yeah, you'd still need to preview the video to find the edit points, but as I understand it, this is essentially how it was done from about 1975-1995 or so using systems like CMX, You'd enter the list of edit points, load up the videotapes and the computer would handle the edit/assembly by itself.

you'd have several source decks remote-controlled by your editing machine, and you'd set ins and outs which end up in a record list tied to one deck (or a few that mirrored the same codes, so you could spit out a few dubs at the same time).

you always had a monitor in front of you - if anyone had to work blind they were doing it wrong.

The point that was made isn't that it can't be done via command line. The point was the nature of video editing is better with a graphical UI. Besides just cutting, how do you do transitions via command line. Also what about sound editing? And any special effects. Anyone who has done this using a video editor today has multiple windows with lots of information being presented. Using a command line to edit video would be like asking someone to use a command editor to layout a magazine or edit photos.

MEncoder definitely capable of extracting part of the movie(*) and combining several ones together. (*)Though IIRC at least in the past MEncoder insisted on frame numbers and wasn't accepting simple times. (I had very little luck with the MEncoder since it often screwed up the A/V sync. But apparently it works for many, since literally all video reencoders for iPhone/PSP/PS3/etc are based on it.)

And that limb does not exist. none of the current pro video editing suites support blind automation.

Honestly some Command line tools that can be scripted would rock for even broadcast media. Let me use one of the new Pro cameras that will use a pair of GSM radios to upload the video I just shot to a FTP server that I can then search the audio for a 1khz tone to mark the begin of the take, cut it there add in a leader then add in the lower third with the text from the metadata (all can be edited in the ca

Actually, this is what kdenlive does: it is a GUI frontend for the CLI MltMelt tool (http://www.mltframework.org/bin/view/MLT/MltMelt). Given, it is one command which does everything instead of multiple small commands, but there is still a separation between the program doing the work and the program providing the GUI.

Yes, but does it actually WORK? The previous versions I have used were all steaming piles of dung. Is this a new, better-functioning release, or is this just another "Hey, look at us linux folk, we can do what the rest of you can, too"?

That is what these usually turn out to be, and it's annoying to download/test a new release to realize it's the same shitty package with a new number tacked on.

If his argument was that ffmpeg's entire philosophy and way of working wasn't what he wanted then your response would be valid. But no, his entire reason for utterly discounting it was one - and only one - bug. Maybe he had more reasons, but the only one he felt worthy of sharing was that one bug.

no it doesn't (ffmpeg that is). but it's much easier to do it wrong than right, and the docs are awful (i often have to read the source to figure out how to use a particular feature).

also, try avxsynth and vapoursynth (the latter doesn't do audio yet, but is very promising and python based so quite GUIable).

but fuck the CLI - linux needs something better than a toy editor and needs something with professional features and a familiar interface. for some reason every opensource video editor seems to think t

Nothing wrong with having a CLI available (and I believe it is) but were I editing video files for most purpose I'd prefer a video interface.

E.g., when editing animations I'd rather use The Gimp then geany, even though I could (probably) do the job on either. (Actually, I've never tried to edit a frame with geany, perhaps it would reject it, or at least give me a read only version. I might need to use a hex editor.)

Why isn't there a suite of command-line tools to handle video clips yet, such as cutting, merging, transitions, variable speeds, inserting still images for a certain length, etc.?

AviSynth [avisynth.org] is a scripting language/library that can do those things, but it's more useful as glue logic than a standalone editor. You really need to see what you're working on when editing video. Even simple effects can involve some manual tweaking to figure out what looks good, and having a real-time random access preview in a non-linear editor is ideal. Seeing audio waveforms is also helpful -- maybe you want to synchronize a video effect with the audio, for instance. I'm currently adding RiffTrax commenta

It's pretty much the best open source video editor out there. It has the right mix of ease of use and functionality - they just need to work on the flakiness. Every now and then when I have need to do video editing, I've looked at the alternatives, and Kdenlive - crashes and all - is the only thing that ever actually does the job.

The commercial Windows based editors may well work a lot better, but I'll never know, because I'll never use any of them.

That's not saying much seeing as any one with a brain and some cash working in video editing, compositing, etc., are embracing Final Cut Pro X, Avid and the others. They sure as hell won't touch this product until it's on par in it's like as Blender is for the 2.68 release.

more cash than brain there. FCPx is the reason sales of Premiere went up so much.

Avid is a little difficult to get started on, but is better for film. there'll always be a place for the offline/online split, because now all the computers can do HD in realtime in finished quality, people are starting to shoot in 4k, 5k, and up. Avid can deal with piddly low-res stuff and makes damn sure it matches the 4k 3D crazy high res stuff without causing the colourist several weeks of panicked conforming where the o

I have been waiting a year and a bit, probably two, for this http://www.youtube.com/watch?v=jEJcPKD9p7A [youtube.com]. Almost everything I have done in the last ten years has been on Avid systems, but I know that Lightworks is also "up there"... ask Scorsese.

Is it really that big of a leap, or is it just perceived as one by the beancounters in charge? Do they even believe there exists a market?

Even you, a frequenter of slashdot, sprout gibberish like "Linux does not have the robust media layer", which in context is complete nonsese. I give you that pulse-audio isn't all that great, but fuck, the audiostack in windows isn't exactly erm.. flawless either. In Linux you have alternatives like jack.

A lot of the visual effects companies tend to run Linux on workstations (except for things like Photoshop, obviously), as well as on the servers. Not sure what Pixar's using on their workstations, but either way 3D modeling and compositing are different beasts than editing.

That said, there are a few commercial video editors that seem to support Linux; I found out about Mistika [wikipedia.org] on Wikipedia. I'm not sure how widely systems like that are used, though.

When i needed to edit some quick video and audio together, I found that a lot of the other offerings on Linux didn't have some simple functionality I wanted, or made it too obtuse and difficult to tweak. Kdenlive seemed to have everything I wanted, and was straightforward for me to pick up. Then there was the crashing. I could live with that, since it only took a few seconds to restart the program. But then a crash corrupted the save file and created a whole mess of things that meant starting over from

Always save to multiple save files. Never overwrite until done. Powerpoint, photoshop, kdenlive, doesn't matter what. If you've got a long term project, save it to a new file every day or hour. Only delete previous ones after confirming current ones, and usually save old ones anyway in case you want to backtrack or show a process to someone.

Yeah, that is a great rule of thumb, but kdenlive seems to take it to a new level. I've never had Powerpoint corrupt a save file, although usually use it to make an hour long presentation once a month for several years now (I've messed things up myself before though... so still make a backup copy once a day). I've heard of complaints with Photoshop corrupting files, but I mainly use Inkscape and GIMP myself, and never had either of them corrupt files either. I still make backups once a day or when about

There are a whole bunch of reasons why I'm not looking at the Windows video editors - but the simplest ones are:

* Linux is my primary desktop environment (and has been since the late 90s). I can use Windows, and am perfectly comfortable doing so, but switching to it means dropping out of what I'm currently doing and rebooting, which is a pain I'd rather avoid.* Video is not my life. I only occasionally want to do anything with video - usually as a project with my daughter. Kdenlive works pretty well (apa

I'm not the AC, but he does have something of a point even if he was a bit rude going about it.

I'd like to think of myself as being quite proficient in Linux. I know my way around the command line well, I use it a lot at work and have a great appreciation for it. I've also used it as something of a hobbyist and tinkering platform at home as well. But the reason I continue to use Windows instead of Linux as my primary platform is simply because it handles virtually all situations that a home user could find

* No waveform view for audio tracks (how are you supposed to sync audio and video?)* No per-clip markers, only global markers. (How are you supposed to find points of interest and sync points in clips before dropping them on the timeline?)

In addition, a useful feature Kdenlive has - that I don't know if Openshot has - is the ability to use unrendered Kdenlive projects as clips. Which means you can create extremely complicated projects, and then only have to do one final rendering at the end. That way you

iMovie and Final Cut work pretty well and you never have to boot Windows to use them. I've used Kdenlive and it has a lot of promise but really it's beta software. I did manage to edit 2 hours of video without a crash though.

I started out with iMovie, but it caused no end of problems for the project I was trying to do, essentially a slideshow with narration. I can't remember what the last straw was, but I switched over to Kdenlive on Linux and although it took a bit of getting used to and the crashes could be extremely frustrating, it worked a lot better for me than iMovie did on Snow Leopard.

I just did a huge video edit on my mac mini with iMovie last week. The newest iMovie works really well unlike the newest Final Cut. I'll probably use kdenlive again when I finish building a new system I'm putting together. Right now the mac mini with quad i7 and 16gigs of ram is just the ticket though. I notice memory usage while editing and it was running over 12 gigabytes being used. Ram and CPU horsepower makes a huge difference with video. The only thing I wish is that the mini could do dual displ

Question, while we're on the subject. I've recently been editing some video, and kdenlive was one of the few video editors I could get to work. However, I've found no way to use the parts of the original video that I haven't modified as they are, without re-encoding. Since most of what I've done is cutting out time ranges from the original footage, using the original data without re-encoding would save a lot of time and quality degradation. Is there any way to do this (using kdenlive or another FOSS video editor)?

Away from Linux (yes, I know!), I've just done a quick-n-dirty edit on two video clips and 15 photos, three separate soundtracks and various transitions in Nero 11. Yes, it was a royal pain in the arse to get the thing to keep the transitions (that was really the only thing that bothered me about the project), but eventually I ended up with a 720p stream (which is the same as the raw video format and some serious pulldown on the images, which are 14MP raw with minor cropping). I had to split the audio and v

Not very userfriendly, but mplayer can snip movies in parts without re-encoding using an edl (edit decision list). You kan bind a specific key to 'cut here' and the watch the movie and press the key at the opportune moment. This wil generate the edl file, whcih you can then use to split the video in parts.

I only use Virtualdub for a frameserver for batch downsampling for mobile devices now, never really used the editing facility in it (though I have used the capture which is pretty good). It takes care of that niggling problem of mobile device converters that can't handle 720p source (such as Atrix 4g (Motorola) and Aura QHD (Android/HTC Sensation) to name two that don't!)

Avidemux will export a video without recompressing it. Just don't change the output format (leave as "copy") then you can make your cuts, and export, and it will export almost as fast as your computer can copy the file. (ie, for a full length movie about 1-2 minutes, with edits intact)

The only caveate with this is that if you cut to close to a keyframe, often times the encoding lose information for the frame, and not exact play back correctly right at the cut, but this is a very minor thing. And if you stud

This seems a strange question. Perhaps I don't understand. You can import clips and re-use the clips anywhere in the time line. You can import the same clip more than once. Or just use snippets in different places. Some modern compression schemas are not necessarily linear. That is why they cannot be concatenated. So the idea of clipping them into sections without re-encoding is unrealistic.

Fair, but my input is Motion JPEG (I did not choose that). Seems to me that it should be possible to copy the frames that are unmodified and only generate new frames for the parts that have been modified (in my case, have filters applied to them).

In fact, the same should be possible to some extent even with more advanced video formats. E.g. if you have I-frames and P-frames, the parts of the video that aren't modified should still be able to be copied, at least when input format and output format are the sa

Lossless cutting (provided that your output codecs match your input codecs) is a feature of the "GStreamer Editing Services" library and thus will be part of the next release of Pitivi (barring unforeseen bugs of course - usual disclaimer applies: no guarantee, patches welcome for issues that may arise, etc.:)

Last time I tested (a year ago), this allowed rendering a project in 7 seconds instead of 5 minutes. Pretty cool if you don't need to apply any effects and just want to shuffle some cuts around quickl

It's impossible to give titles "momentum" (for kinetic texts, etc). And the devs acknowledged this is a fundamental design flaw that it'd be difficult to change now.

There aren't many templates to choose either.A friend of mine told me that with a Mac making a title is only a matter of choosing a template from a list. You can make a title with a growing flower around it, etc.So not only it needs to advance in the technical department, but on the artis

+1. Yes, it is to integrate the cross-platform video editing "engine" that has been built from the ground up for cross-platform, multi-threaded performance. It is written in C++, uses cross-platform build tools, and utilizes many amazing open-source libraries, such as FFmpeg & LibAV, JUCE Audio Library, and ImageMagick.
